Preliminary results from osteosynthesis using Ender nails by means of a percutaneous technique, in humeral diaphysis fractures in adults

ObjectiveTo demonstrate the clinical and functional results from treatment of humeral diaphysis fractures using Ender nails.MethodsEighteen patients who underwent osteosynthesis of humeral diaphysis fractures using Ender nails were evaluated. In addition to the clinical and radiographic evaluations, patients with a minimum of one year of follow-up were assessed by means of the Constant, American Shoulder and Elbow Surgeons (ASES), Mayo Clinic and Simple Shoulder Value (SSV) functional scores, and in relation to the degree of satisfaction with the final result. The fixation technique used was by means of an anterograde percutaneous route.ResultsAll the patients achieved fracture consolidation, after a mean of 2.9 months (ranging from 2 to 4 months). The mean Constant score was 85.7 (ranging from 54 to 100) and the mean ASES score was 95.9 (ranging from 76 to 100). All the patients achieved the maximum score on the Mayo Clinic scale.ConclusionFixation of humeral diaphysis fractures using Ender nails by means of a percutaneous technique was shown to be a method with promising preliminary results.

ResumoObjetivoDemonstrar os resultados clínicos e funcionais do tratamento da fratura diafisária de úmero com uso das hastes de Ender.MétodosForam avaliados 18 pacientes submetidos à osteossíntese da fratura diafisária de úmero com uso da haste de Ender. Além das avaliações clínicas e radiográficas, os pacientes com no mínimo um ano de seguimento foram avaliados pelos escores funcionais de Constant, American Shoulder and Elbow Surgeons (Ases), Mayo Clinic, Simple Shoulder Value (SSV) e quanto ao grau de satisfação com o resultado final. A técnica de fixação usada foi por via anterógrada e percutânea.ResultadosTodos os pacientes obtiveram consolidação da fratura, com média de 2,9 meses (variação de dois a quatro). A média do Score de Constant foi de 85,7 (variação de 54-100) e a do ASES de 95,9 (variação de 76-100) e todos obtiveram pontuação máxima pelo escore Mayo Clinic.ConclusãoA fixação das fraturas diafisárias do úmero com o uso da haste de Ender pela técnica percutânea demonstrou ser um método com resultados preliminares promissores.
